LOUIS PATTERSON, OF SOUTH PUEBLO, COLORADO.

NAIL-PLATE FEEDER.

SPECIPICATIOF forming part of Letters Patent No. 322,963, dated July 28, 1885.

Application filed May 14, 1885. (Model.)

To all whom it may concern:

Be it known that 1, Lotus PATTERSON, a citizen of the United States, residing at South Pueblo, in the county of Pueblo and State of Colorado, have invented a new and useful Nail-Plate-Feeding Machine, of which the following is a specification.

My invention relates to improvements in nail-plate-feeding machines by which the nailplate is rotated and fed automatically to the cutters of a nail-machine; and the objects of my improvements are, first, to transmit motion from the nail-machine to the feeding-barrel of the nail-plate feederby means of a rockshaft; second, to afford facilities for the proper turning of the feeding-barrel a half-revolution and holding it rigid in proper position while each nail is being cut off; third, to afford facilities for the proper feeding forward of the nail-plate in the cutters of the nail-machine; fourth, to afford facilities in a nail-plate nippers and rod whereby the nail-plate is kept in proper position after it has been fed through the feeding-barrel until the nailplate has been fed up sufficiently far; fifth, to afford facilities for the proper placing of the nail-plate within the feeding-barrel, and, sixth to afford facilities for the proper adjustment of the nail-platefeeding machine to the nail-machine by means of a base-plate for lateral adj ustmentand vertical pivot for vertical adjustment. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a perspective of the nail-platefeeding machine, shown in connection with a nail-machine. Fig. 2 is a vertical section drawn through the axis of the feeding-barrel. Fig. 3 is a section through barrel and slotted collar at right angles to their axes. Fig.4 is an elevation showing the mechanism for giving a forward feed to the nail-plate, with the side plates or checks left off. Fig.5 is a perspective view of the slotted collar, with its two side cams and face-cam. Fig. 6 is a bottom view of the base-plate-supporting device, shown in connection with the under side of a nail-machine. Fig. 7 is a view of the feeding-nippers and rod with guide-plate. v

Similar letters refer to similar parts throughout the several views.

1) E represent the frame of the nail-machine,

which may be of any suitable construction, and carries uprights or bearings F F-one on each side-in which the driving-shaft is j ournaled. Motive power is applied to one end of this shaft, while to the other end is keyed a crank-wheel, J, to the crank-pin of which the upper end of a connecting-rod, L, is pivoted. The lower end of rod L is pivoted to the leverarm V. This description simply embraces the working parts of the common nail-machine, which are necessary to show the precise manner in which my invention is attached to those parts. A stud, W, is turned upon or screwed into the end of the pivot at the lower end of the rod L.where rod Lis pivoted to the lever-arm V. The lower end of the connecting-rod Ais pivoted to the stud WV. The upper end of rod A is pivoted to the outer end of the arm B of the rock-lever formed by the two arms B B, connected by the rock-shaft (J. The outer end of arm B is pivoted to the upper end of the connecting-rod A. The lower end of rod A is pivoted to a stud screwed into the reciprocating rack M. The rock-lever formed by the arms B B and rock-shaft O is supported by a bearing, N, attached to the frame D E of the nail-machine. The rack M is held in place by and reciprocates in grooves in the casing 2 2, as shown in Fig. 1. Studs 22 are screwed, .at equal distances apart, into the rack M, and mesh into the slots in collar S, as shown in Fig. 3. The casing 2 2 forms the bearings for the feed-barrel Q. The slotted collarS is made to fit loosely on barrel Q, permitting it to have a reciprocating rotary movement, and carries on its face a cam, 7, and upon its side two cams, 17 17. (Shown in Fig. 5.) A collar, 3, is turned upon barrel Q, and at opposite "points on said collar are fitted studs 5. (Shown in Fig. 2.) Upon the side of collar 3 are corresponding cams to those sho wn on collar S in Fig. 5. A pawl, It, is pivoted between the casing 2 2, and is held down upon barrel Q, by a spring, 23. A spring, 8, is placed between one side of the casing 2 2 and the collar S, serving to keep collar S pressed against collar 3 on barrel Q. On the large end of barrel Q, outside of easing 2, is fitted a collar, T, having two cams, 24 24, on its face at opposite points on the collar, and engaging with the spring or pawl 25.

in. Fig. 6.

The operation of the rack M, collar S, and barrel Q is as follows: By the upward movement of rack M, collar S is made to rotate forward a half-revolution, cams 17 17 mesh with [0 ward, disengaging its side cams, and by their natural friction, combined with the spring 8, gives collar S an oscillating motion on barrel Q. To permit this movement of collar S, slots are made in collar S to afford ample space in which studs 22 can work. During the backward movement of collar S barrel Q is held in position by pawl 25, meshing with cam 24 on collar T, and during the same movement cam 7 on collar S is brought in contact with and raises pawl R, and keeps it raised a sufficient time for stud 5 to pass under pawl R.

Upon the inside of barrel Q, at its large end and opposite to each other, are inclined guides 4 4, for the purpose ofguiding the nail- 2 5 plate into a proper position to be fed through the small end of barrel Q. A vertical pivot, I, is attached to and extends down from the under side of the casing 2 2, fitting loosely in a hinged socket, 1?, (shown in Fig. 2,) permit- ;0 ting barrel Q, with its connected mechanism,

to have a lateral adjustment, and held rigid by means of the screw 26.

Barrel Q, with its connected mechanism, can be given a vertical adjustment by means of ,5 the screw 27, passing up through the bottom of hinged socket P, and pushing against the lower end of the vertical pivot I.

To the under side of the nail-machine frame D E is attached, by means of headed screw- .0 bolts-K K, the base-plate O. A slot, 29, is

formed in base-plate 0, through which passes bolt K, and being pivoted by bolt K it thus permits a slight lateral adjustment of baseplate 0 and itsoonnected mechanism,as shown Lugs are formed upon the front end of plate 0, between which the hinged socketP is hinged. (Shown in Fig. 6, and at 28 in Fig. 2.)

To the under side of the casing 2 2 is ato tached, by means of screws 15, as shown in Fig. 2, the arm U, sustaining the feed mechanism, as shown in Fig. 1- A slot, 31, is made in said arm, through which passes the forward screw 15, thus permitting a slight lateral ad- 5 justment of the arm U and its connected mechanism. (Shown in Fig. 6.) Upon the forward end of arm U are elevated sides 9 9. A rock-shaft, 12, passes through perforations in sides 9 9 and arm U. Upon rock-shaft 12 are 9 two lever-cams, YY, that work within recesses in the arm U, as shown in Fig. 4, and on the inside of sides 9 9, as shown in Fig. 6. Upon the top of sides 9 9 are pivoted links X XX X. Upon the top of arm U, inside of sides 9 9, 5 are jaws 10 10. To the top of jaws 10 10 links X X X X are pivoted. (Shown in Fig. 1'.)

The working ends of the lever-cams Y are made rounding, and fit into corresponding rounded recesses injaws 1O 10. (Shown in Fig. 4.) A lever-arm, H, is attached to the end of rockshaft 12 by a set-screw, 32, (shown in Fig. 1,) or it may be keyed, if desired. Arm H is supported byaspring, 33. (Shown in Fig. 6.)

Motion is given to arm H by means of a slotted bar, Z, attached to the rack M by means of a headed screw, 34, passing through a slot, 35, in the slotted bar Z, permitting a slight vertical adjustment ofsaid bar. (Shown in Fig. 1.)

Attached to the extreme end of arm U is a spring, 37, made in the form of a horseshoe. 1t springs upon the feeding-rod 16 with sulficient force to keep rod 16 from slipping forward when the feeding-barrel Q and its connected mechanism are being thrown backward from the cutters of the nailmachine by the rod 14 connected to the eccentric 13 attached to the driving-shaft of the nail-machine. The casing 2 2 is connected by means of a rod, 14, to an eccentric, 13, on the driving-shaft of the nail-machine, by means of which the feeding mechanism is given an oscillating motion, being necessary to give the nail-plate 36 sufficient clearance from the cutters of the nail-machine.

For the purpose of keeping the nail-plate in proper position after it has passed through the small end of the barrel Q, I place a plate, 21, between the feeding-nippers 38 and feedingrod 16, connecting the two parts together, as shown in Fig. 7. The feeding-barrel Qtapers to a small opening, as shown in Fig. 2,through which pass the nail-plate 36 and nippers 38. The plate 21,being on the same horizontal line with the nail-plate 36, it follows as the plate 21 comes into the small opening of the feedbarrel Q,it serves to keep the nail-plate 36 in correct position while it is cut into nails.

The operation of the device for feeding forward the nail-plate is as follows: The reciprocating motion of bar Z reciprocates arm H, which in turn rocks the rock-shaft 12, thus reciprocating levercams Y Y, which in turn reciprocate j aws 10 10. Jaws 10 10,being pivoted by the links X X X X, it follows when jaws 10 10 are moved forward said links cause the said jaws to close toward each other, and thus grasp the feeding-rod 16, carrying it forward at theright time and distance for a nail to be cut from the end of plate 36.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a nail-plate-feeding machine, with the frame and driving-shaft of a nail-machine, of the stud W, arms A, A, B, and B, the two latter connected to the rockshaft 0, and the rack, M, all constructed and arranged to impart rotary motion to the feedbarrel Q, all substantially as set forth.
